PERPETUAL MOTION. Regenerating pendulum. A,B,E,Fis a frame connected by C, D, a crossbar, through which runs g, a pen-dulum hung on a pivot, C. This pendu-lum has two arms, one, a, measuring fivefeet, and the other, b, one foot in length,connected so together to form a leverwith a long and short arm, whose fulcrumis c. This pendulum has a weight of twopounds at its end. K, K are two shortlevers having a joint in them to allowthe pendulum to pass them one way, butnot the other, without moving them, whosefulcra are d, d, by which they are connected with A, B. From these run cords, /, /, over pulleys, w, m, whichcords are connected (for the purpose of drawing them up into catches)with h, h, springs throwing with a power of thre
